<p class="level0">mk-ca-bundle [bilnqtuv] <span Class="emphasis">[outputfile]</span> <a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0">The mk-ca-bundle tool downloads the certdata.txt file from Mozilla's source tree over HTTP, then parses certdata.txt and extracts CA Root Certificates into PEM format.  These are then processed with the OpenSSL commandline tool to produce the final ca-bundle file. 
<p class="level0">The default <span Class="emphasis">outputfile</span> name is <span Class="bold">ca-bundle.crt</span>. By setting it to '-' (a single dash) you will get the output sent to STDOUT instead of a file. 
<p class="level0">The PEM format this scripts uses for output makes the result readily available for use by just about all OpenSSL or GnuTLS powered applications, such as curl, wget and more. <a name="OPTIONS"></a><h2 class="nroffsh">OPTIONS</h2>
